SPECIFICATION forming part of Letters Patent No. 380,542, dated April 3, 1888.

Application filed February 14, 1887. Serial No. 227,466. (No model.)

,To all whom it may concern:

Be it known that I, WALES ALDRICH, of Dayton, in the county of Montgomery and State of Ohio, have invented certain newand useful Improvements in Cash Registers and Indicators; and I do hereby declare the following to bea full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

My present invention relates to that class of machines which perform the functions of serving as a check upon dishonest employes who handle the cash in a bnsinessestablishment and as a means for keeping an accurate account of the cash receipts during any given period. u

The machine which I have designed for carrying out my invention embodies a series of keys each represent-ingaparticular amount, a series of targets or visual signals corresponding to the series of keys and adapted to be ex posed when said keys are operated, an alarm mechanism, a registering mechanism, and a mechanism by means of which the cash-drawer is released, the whole being so arranged as that when a cash purchase is made and the key or keys corresponding to the amount of the purchase is or are operated a target or targets indicating the amount will be exposed to the view of both employ and purchaser, the alarm will be sounded, a record made of the transaction upon the registering mechanism, and the money-drawer released or unlocked, so that the amountreceived from the purchaser may be deposited therein and change made, if

necessary.

I will first describe my machine at length, and will then point out what I deem its particular features of novelty in the clauses of claim at the end of this specification.

Referring to the accompanying drawings, Figure 1 represents a perspective view of a machine constructed in accordance with my invention; Fig. 2, aside view of the same with the casin g removed; Fig. 3, a perspective view of a portion of the mechanism, showing one key-bar, its corresponding target, and the intermediate mechanism for operating it, the alarm mechanism, and portion of the registering mechanism. Fig.4 is ahorizontal section taken on the line 00 w of Fig. 2, showing in dotted lines the position the parts occupy when the key-bar is pulled out, the tabletexposed, and the registering device operated. Fig. 5 is atop plan view of the mechanism shown in Fig.

2. Fig. 6 is a detail View showing in elevation the registering mechanism. Fig. 7 is a View of the gear and the actuating-spring for returning or resetting the registering mechanism; Fig. 8, a detail view of the bell and the trip mechanism applied to the hammer thereof. Fig. 9 is a longitudinal vertical section taken through the casing of the machine, and showing particularly the means forlocking and re leasing the money-drawer.

Similar letters of reference in the several figures indicate the same parts.

, The letter A indicates a suitable casing constructed of wood or other material, and of a form which, aside from its adaptability to the inclosed mechanism, may be varied to suit the taste of the designer.

Glazed openings B are provided at the upper portion of the casing for the exhibition of the targets or visual signals employed in the machine, other glazed openings, 0 0, being provided at the sides to enable the body of the mechanism to be inspected, as well as an opening, 'D, closed by a hinged cover, E, for enabling the register to be exposed to view and be reset when necessary. This cover E is preferably kept locked, so as to be accessible to no one but the person holding the key. At the bottom of the casing is arranged a drawer, F, which, when in place, is adapted to be held closed by a top, G, that is itself locked and unlocked by means of devices to be hereinafter described.

Within the casing is arranged a metal frame, H, that is adapted to receive and maintain in their proper relations all of the operative parts of the machine, except some of the devices shown in Fig. 9, employed for locking and unlocking the money-drawer. For convenience of description this frame H and the mechanism borne by it are shown removed from the casing in most of the figures.

Referring particularly to Figs. 2, 3, and 4, K will be found to represent a series of horizontal bars arranged one above the other and supported at front and rear upon stationary arms or fingers I 1, formed upon the metalframe. These bars I term, for convenience, key-bars. Each of them near its outer end is pivoted to a hinged link, L, which serves to guide and steady it in its reciprocating movements and allow the lateral movement necessary to cause the key-bar to properly operate upon the vibratory bar and the shaft to which the registering mechanism is geared, and at its extreme outer end, outside of the casing, it is provided with a loop or eye, K, to enable the operator to conveniently operate it with his finger. On this eye or loop K is formed or affixed the figure or number which the particular bar is intended to designate in practieally using the machine.

M M, &c., Figs. 2 and 3, represent a series of bell-crank levers, as many in number as there are key-bars. Each of these bell-crank levers is mounted so as to turn freely upon a vertical rod or pivot, N, and one of the arms, at, projects in the path of a lug or projection, 1K on its corresponding key'bar K, while its other arm, m, bears a vertical rod or staff, 0, which carries at its upper end a target or tablet, 0, upon which is marked on both sides a figure or number corresponding to that on the end of the key-bar. All the targets nor mally stand swung around to one side out of line with the opening B in the casing; but when any one of the key-bars is pulled the projection K upon it strikes the arm in of the co-operating bell-crank lever and turns said lever on its pivot, thereby bringing the target carried by said lever to the opening B, where it will be visible to both the operator and the purchaser whether they both be at the front or one at the front and the other behind the machine.

P represents a bar mounted so as to turn freely upon a vertical rod or pivot, P, and having a series of rigid lateral arms orfingers, 1), that project beneath the series of keybars and are adapted to be operated upon by lugs or projections K, formed on said key-bars, as shown in Figs. 2 and 3. These arms 1) are an ranged spirally upon the bar P, the effect of which isto cause the topmost arm ofthe series to stand normally at the greatest distance from its co-operatinglug K 01i the corresponding keybarand the lowest ofsaid series of arms to stand nearest to its cooperating lug, so that while a considerable extent of movementof the uppermost key-bar will be required in order to bring its lug K into engagement with the arm p, only a comparatively short movement of the lowest key-bar will be necessary to render it operative upon the armp. The links L and bar T causing the projections on the key-bars to move in the arc of a circle of which the center of barP is the center render it necessary to arrange the arms p in a spiral line.

XVhenevcr either of the key-bars is pulled or withdrawn to its full extent, its lug K" strikes the arm 1) in its path and turns the bar P 011 its axis a greater or less distance, accordingly as said engagement between the lug and arm occurred sooner or later, thereby causing an arm, Q, secured to the upper end of the bar P and bearing a spring-pressed pawl, Q,which is in engagement with a ratchetwheel, R, to rotate said ratchet-wheel and through it set in motion the driving-gear S of a registering mechanism, the construction of which will be farther on explained. To an arm, P, on the lower end of the barP is connected (by alink, P) a spring, P, Figs. 3 and 4:, which is put under compression each time the bar P is turned and tends to bring said bar back to normal position.

T represents a bar mounted on a vertical axis, T, at the rear of the frame H and having a series of arms, t, with which the T-shaped ends of the key-bars are adapted to engage. This bar T has an arm, i, Fig. 4-, to which a spring, 25, is connected by means of a link, '6. Upon the pulling of any one of the key-bars this bar T is vibrated on its pivot against the tension of said spring l The position the parts occupy when the key-bar is pulled is shown in dotted lines, Fig. 4.

The uppermost arm of the bar T is provided with a cam projection, 1 which, when the bar is vibrated, is adapted to engage with a depending arm, U, secured to a rock shaft, U, as shown clearly in Fig. 3. This rockshal't U bears at its opposite end a tripping arm or lever, U, that is adapted to engage with a pivoted latch, U, which operates upon the arm U on the hammer U of a bell, U Every time the bar T is turned in response to a pull upon one of the keybars the shaft U is rocked and the bell is rung. Also mounted on the rock shaft U is an arm, V, Figs. 3, 2, 5, which bears at its extremity a friction-rol er, o, and normally standsjust above the upper end of a lever, V, pivoted to the side of the casing, as shown in Fig. 9. The lower end of this lever extends beneath an adjiistable stop, V, located on a vertically'sliding bar or bolt, V, whose lower end is adapted to engage with anotch, V", formed in the top G of the moneydrawer, as shown. Through a cross-piece, G, secured to this top G, passes a rod, G, which is secured to the back of the casing, and arranged upon this rod between the casing and the said cross-piece G is a spiral spring, G.

Vhen the rock-shaft U is turned in eonsc quence of a pull being made upon one of the key-bars, the bar V will, through the described connections, be raised out of engage ment with the notch V", and the spring G, asserting itself, will force the top G of the money-drawer forward, and by thus releasing the drawer from the restraining effect of the shoulder V" of said top enable the drawer to be pulled out.

From what has been stated itwill be apparent that starting with the machine in normal position and with none of the targets or tablets exposed at the openings in the upper part of the casing, a pull upon any one of the keybars will cause, first, a corresponding target or tablet to be exposed; secondly, a turning of the bar P and a registration upon the registering mechanism; thirdly, the ringing of the bell, and,fourthly, theunlocking of the moneydrawer. Upon the release of the key-bar so pulled and the pushing in of the money-drawer and its top all the parts will resume their first position, excepting the registering mechanism, which retains a record of the transaction, and the target or tablet,which remains exposed at the openings. When anotherkey-bar is pulled, the operations are all repeated, save that the target or tablet is withdrawn from view and another one corresponding to the key bar I pulled is exhibited in its stead, and that the registering mechanism is given a greater or less extent of movement, according to the amount'designated.

The withdrawal of the target or tablet from the opening is effected by the mechanism and in the manner which I will now describe: Pivoted at W to the top of the metal frame, Figs. 2, 5, is a lever, \V, to the rear end of which is hinged a gravitating piece or latch, W the forward end of which lies in the path of a stop or projection, W, on a plate, W, that is adapted to be reciprocated transversely of the frame and to carry with it a vertical rod, Z, which extends down between the arms of the bell-crank levers M, as shown in Fig. 4, and is stepped in a swinging arm, Z, hinged to the rod or pivot N, as shown in Figs. 2, 3, 4. The piece or latch V stands in the path of the cam projection t on the arm of the vibratory bar T, and when said bar T is vibrated in response to a pullgupon a key-bar the said cam projection, striking the said piece or latch W", causes the lever \V to be turned on the pivot W and its inner end to strike the projection W on the plate lV, and through said plate cause the rod Z to swing around, and, engaging with the inner arm of the bell-crank lever carrying the target or tablet exposed at thefrom view is the first to be performed when a key-bar is pulled and does not interfere at all with the orderly and timely exposure of the next target or tablet which is to indicate the manipulation of said key-bar.

The lever NV is reset automatically upon the return of the cam projection i to normal position, and the sliding plate W and tabletretracting rod Z are brought back to normal position by the swinging around of the bellcrank lever, which'brings the next target or tablet to view.

I will here state that to prevent any possible interference of the targets or tablets with each other I have constructed the arms of the successive bell-crank levers which bear the targetshafts of different lengths, as shown in Fig. 2, and have arranged guides o for directing the staffs in their movements for separating them, and, by affording them lateral support, preventing them from becoming bent and interlocked. These guides are preferably composed of strips secured at one end to the frame,and are bent in the arc in which the staffs of the tablets move, one strip being situated between each pair of staffs.

The registering mechanism is constructed as follows: With the gear-wheel S, hereinbefore referred to, there is meshed a small gear, S, mounted on a long pinion-shaft, S". This pinion-shaft is adapted to be meshed with a gear, S on a shaft, S, which shaft has also a pinion, S which engages a gear, S, on ashaft, S, that is in turn provided with a pinion, S, that meshes with a gear, S", mounted on a shaft, S, and connected through a volute spring, S, to a stationary drum, S", as shown in Figs. 6 and 7. The pinion-shaft S has its bearing in the metal frame H, as shown in Fig. 6;but the shafts S and S have their hearings in and are supported by a supplemental frame, S, which is supported in a plate, S mounted on the frame H above the gears S S, as shown in Figs. 5 and 6. The pinion-shaft S projects up through suitable openings in the plate S and the frame S and is kept normally in engagement with the gear-wheel S by the action of a spring, S interposed between the flange of the plate S and the end of the frame S On the upper end of the pinionshaft S is secured an indicator, S, which co-operates with adial laid off in divisions numbered from 0 to 9, inclusive, and is adapted to keep a register of transactions varying in amounts from one to nine cents, while upon the upper ends of the shafts S S S respectively, there are secured other indicators, (lettered S S S respect ively,that are adapted to co-operate with other dials designed to register transactions varying in amount from ten to ninety cents, from one to nine dollars, and from ten to ninety dollars, respectively.

Now, the key-bars are ten in number and are designated on their endswith figures from one to ten, inclusive,the uppermostbar being numbered 1, and so on in order to the lowest one, which is numbered 10. Whenever one of'the key-bars is pulled out-the fifth bar, for in stance, for a fi ve-cent transaction-the fifth bar 10 of the series of arms projecting from the bar P will be engaged by the lug K on said fifth keybar and will cause the vibration of said bar P a distance sufficient to cause the pawl P to advance the ratchet-wheel R, and through the intermediate gearing turn the pinion-shaft S until the indicator on its upper end uncovers the figure 5 of the dial beneath it. If the next transaction be a ten-cent transaction, keybar No. 10 will be pulled and the registeringtrain will be operated so as to cause theindex S to move around and stand between the figures 10 and on the second dial and the figure 5 on the first dial, the indicator on this last-named dial, which before stood at 5, having been by the recordation of the ten-cent transaction caused to make a complete revolution and brought back to starting-point. If.

the next transaction should be a dollar trans action, the key-bar 10 will have to be pulled ten times, and if a ten-dollartransact-ionahundred times, the registry of these items being effected on the third and fourth dials, as will be readily understood.

Normally the spring S, Fig. 7, is kept par.- tially wound up, and the gear S, to which said spring is connected, is kept from backward movement by the engagement of a stop, S located on the under side of the said gear, with a spring-detent, S, secured to the frame S, as shown in Fig. 6. The principal function of this spring S is to operate upon the train of gearing and run the register back to zero when it is so desired. To make this plainer, it should be borne in mind that each time the gear S" is turned. as a consequence of the manipulation of the key'bars the spring S is wound up more and more, and when, at the end of the days business, for instance, it is desired to reset the register to zero the frame S is given a slight longitudinal movement in the direction indicated by the arrow, Figs. 5 and 6, sufficient to compress the spring S and disengage the pinion S from the pin ion-shaft S whereupon the spring S, asserting itself, will cause the gear S" to rotate backward till its stop S comes again into contact with the spring-detent S, or, in other words, till all the indicators operated by the connected train are brought back to zero. lhe shifting of the frame S to effect this resetting operation can be accomplished either by moving said frame positively by hand or by turning a cam-lever, S, Fig. 5, till the pressure of its canrsurface against the adjacent wall of the casing eifects the desired movement.

It should be stated that the openings in the frame S through which the pinionshaft S passes, are made large enough to permit of the shifting of the said frame as above described.

Should the machine be so frequently used before resetti ng as to cause the gear S to make a full revolution or more than a full revolution, the stop S will depress the spring-detent S' and pass by the same, thus allowing the gear to move on unintcrruptedly, and when subsequently it is desired to reset the register back to its normal state, it is only necessary, in addition to moving the frame S so as'to throw the gear S out of mesh with the pinion shaft S", that the spring'detent S be depressed, so as to let the stop S pass by on its first backward revolution and then arrest it on its next revolution. A pin, S projecting above the frame S and connected to the spring-detent, maybe employed as a meansof operating said detent.

Owing to the necessity of pulling more than one bar or of pulling the same bar a number of times to register a transaction involving an amount greater than ten cents, I preferably employin practice three mechanisms substantially like the one herein shown and described that is to say, one for use in dealing with amounts from one to nine cents, inclusive, an-

other with amounls of from ten cents to ninety-nine cents, inclusive, and still another with amounts including a dollar and multiples thereof, after the manner of the invention described in my patent, No. $2,059, dated May 18, 1886. These several mechanisms I preferably arrange alongside each other within a common casing, so that a single rocleshaft, U, may be employed for ringing the bell and releasing the money-drawer top. \Vhere such duplication of the mechanism is made, I preferably employ a separate register for each mechanism.

Having thus described my invention, what I claim as new is 1.
